spoot-MAKING MAcl-HNERYI SPECIFICATION forming part of Letters Patent No. 740,422, dated october e, ieee.

Application filed April 30| 1903.

nois, have invented a certain'uew and useful l Improvement in Spool-Making Machinery, (Case No..8,) of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to spool-making machinery, and has for its object the provision of a machine for automatically manufacturing spools, particularly such spools as are adapted to have wire wound upon them and then to be slipped over the coreof an electrolnagnet, the material of the spool serving at the same time as an insulating medium between the wire and the electromagnet-core.

I shall describe my invention as applied to a machine particularly'adapted to automatically manufacture out of paper, liber, or other insulatingk material spools, such as are described in my copending application, Se,- rial No. 143,284, led February 14, 1903. I do not wish to be limited to this construction, however, as my invention may readily be ap.

plied to machines for manufacturing articles similar to such spools.

In accordance with my invention the ruachine consists, primarily, of a suitable support, upon which is mounted a horizontal shaft driven from any source of power. A plurality of cam-pulleys are mounted upon this shaft, one of said cam-pulleys serving to reciprocate longitudinallya shuttle-bar across the top surface of the machine. Each of the other cam-pulleys mounted upon the hori- Izontal shaft serves to produce vertical and lateral motion of mechanism which performs one or more of the steps of manufacture of a spool. A shuttle in conjunction with the shuttle-bar serves to carry the material, such as paper, from which the spool is made from 'a position to be operated upon by the mechanism of the first stages andthence to each of the other mechanisms to pass through the other'stage's of manufacture,a finished spool being deliveredat the end of each stroke of 'seriez' No'. 154,966. (No man.)

the reciprocating shuttle. The paper, which eventually composesthe core of the spool, is vfed into the machine-for instance, from the left thereof--by feeding mechanism operated by the first cam of the series of cams, whereupon a suitable length thereof is sheared o and folded into a rectangular tube having the shape of the core. This folding action is accomplished by mechanism also operated in couj unction with the first cam, as will be hereinafter more fully described. This tube is now carried by theshuttle-bar toV be operated upon by flaring mechanism controlled by the second cam. This flaring mechanism engages the edges of the tub'e and iiares out the ends of the walls of the tube to form flaps, against which the flange-pieces of the spool are evenaA narrow band, one of said bands being fed.

from each side of the machine for supplying flange-pieces for each end of the core portions. The paper is fed by punch-openings adapted to receive two setsof punches operated and controlled by the' third cam on the horizontal shaft. lThese sets of punches are symmetrical, one ofv said sets cutting pieces ont of the paper to leaveopenings having the size of the opening in the core portion. The other set of punches cuts from the paper inished flanges, as will hereinafter be more fully described, and carries the flanges and presses them against the iiaps on the core portion, which portionby this time is disposed in alinementwit-h this setof punches. A Wet sponge The iiange-pieces are punched is disposed in the path of the paper between tion. The flange parts previous to being punched out of the paper have been moistened by the sponge and upon being pressed against the, gummed surface of the vflaps ad here thereto.

A horizontal shaft 1 is disposed in suitable bearings carried upon the machine-support 2 and may be driven from any source of power A plurality of cam-pulleys'4, 5, 6, and 7 are rigidly mounted upon said shaft, the cam-pulley 7 being preferably disposed at the right end of said shaft, the -periphery thereof being provided with a series of camways 8, 9,10, l1, and 12, in which ways a cam-roller 13 is adapted to travel. Camways 14 and 15 are also disposed upon the periphery of the cam-pulley 7 and are adapted to guide a cam-roller 16. The cam-roller 13 is journaled to the rear end of a shuttle-bar 17, provided with flanges 18 18, which t in guideways 19 19, in which` said shuttle-bar is reciprocated as'said cam-roller travels through said camways. A shuttle 2O is composed of side Walls 21 2l, disposed one on each side of the shuttle-bar and pivoted thereto at 22 22. Upwardly-extending arms 23 23 on said side walls are connected by a bridge-piece 24. A lock-bar 25 is disposed above said shuttle-bar and is adapted to move longitudinally thereon,being retained against said shuttle-bar by means of a bridge 26, secured to lsaid shuttle-bar, and by the bridgepiece 24. A post 27 is secured to the top of bridge 26, a spring 28 intervening between said post and another post 29, secured to the locking-bar. A spring 28 is interposed between said post 27 and the bridge 24. In the working position the shuttle-bar, shuttle, andv locking-bar are disposed as shown in Fig. 3, the locking-bar being held in a forward position against `said shuttle-bar by means of latching mechanism consisting of a latch 30, mounted upon a pivot 31 at the rear end of A bridge-bar 35 extends between the side walls 2l at the forward end of the shuttle, and when said shuttle is depressed, as shown in Fig. 3, said bar rests in a notch 36 in the shuttle-bar, the'nose portion 37atthe forward end of the locking-bar being in position above said bar, therebylocking the shuttle in place against the tension of the spring 30. Another notch 3Sin the forward end of the shuttle-bar is cut large enough to accommodate the core portion of the spool. A notch 39 is cut in the forward end of each of said side walls, the contour of said notch being such as to receive the flange portion of the spool.

Invthe idle position the shuttle-mechanism partsare arranged as shown in Fig. 4, having reached the extreme right of the machine, the rear end 40 of the shuttle having passed beyond the rear edge 41 of the machine-bed. As shown, a finger 42, projecting from the periphery of the cam-pulley 7, which travels in the direction shown bythe arrow, has just passed ont of engagement with the latch 30, disengaging said latch from the detent 33, whereby the locking-baris released and drawn back by spring 28. The nose 37 in this position has retreated beyond bar 35, thus allowing the shuttle to be snapped upward by the spring 30, the rear end 40 of the shuttle depending over the edge 4l of the machinebed. To cushion the locking-bar asit is drawn suddenly backward, I provide bars 43 43, said bars being secured or otherwise fastened to the rear of `guide-walls 19, extending rearwardly therefrom. A cross-piece 44 at the end of said rods is faced with a rubber cushion 45, which receives the impact of the locking-bar.

Having thus described the shuttle mechanism which carries the spool material from one stage of operation to the other to be acted upon by the various mechanisms in said stages, I shall now describe such mechanisms.

The paper 46, from which the core portion is formed is fed, from a roll 47, rotatably mounted upon an arm 48, extending upwardly at the left of the machine. In Figs. 1 and 2 I have shown the mechanisms in position just after a completed spool has been delivered, the cam-pulleys traveling in the directionindicated by the arrows. Oam-pulley4 is adapted to actuate the feeding mechanism 49 and the cutting-off and folding mechanism 50. As seen in Fig. 6, said cam-pulley has secured to its left face a cam-roller 51, adapted as said pulleyrevolves to raise a cam-post 52, which actuates the feeding mechanism. This feedingmechauism consists of a large feed-wheel 53 and a` smaller wheel 54, between which wheels the paper is fed. A ratchet-wheel 55 is secured to feed-wheel 53 and is engaged by a pawl56, pivoted at the upward end of cam- IIO position is shown in Fig. 9.

post 52. This feeding mechanism is adjusted to feed a certain length of paper during each revolution of the cam-pulley.-'f A spring 57,

remaining portion 59 thereof being straight and disposed at right angles to the axis of the pulley. A cam-roller 60, secured to a cam-" post 61, is adapted to travel in said camway. Arms 62 62 extend symmetrically upward from said cam-post, one at 'each side of the machine, the ends thereof being bifurcated As best seenin Figs. 8, 9,10, and 11, pitmanlever members 63 63 are mountedat one elbow end thereof upon pivot-pins 64 64, extending across the bifurcated ends ofthe arms 62.

The other elbows of said pitman-levers areV pivoted at 65 65 to the forward end of bearings 66 66, which bearings form the-forward part of a hinged frame 67. The hinged member is hinged at the left of the machine-frame in bearin gs 68 and has forwardly-entendi ng arms,

69 69, each. armV terminating in one of the bearings 66, a space intervening between said bearings. A bridge-piece 70,.,extends between legs 69 69 to the' rear'of the' bearings 66 and a distance above them. Secured to the front face of said bridge is a blade 71, the edge 72' bearings 66 and shaped at their forward end into flat bars 74 74. The bearings engaging pivots 64 are in the shape of diagonal slots 75, and the bearings engaging the elbow-pivots 76 76 are also slotted to prevent binding'.

As the cam-post 61 and pivot-arms 62 are puiled downward as cam-roller 4 rotates in the direction of the arrow the first operation caused thereby will be to pull the pitmanlevers downward by virtue of slots 75,thu`s to force rods 73 73 inward to bring the dat bars 74 together. When the pivots 64 reach the bottom edge of the slots 75, the hinged frame 67 will be brought downward, carrying with it-blade 71 and the dat forming-bars 74. This this position assumed by the forming-bars the Vforward end of the shuttle-bar and shuttle will be at the beginning of a stroke, asl

shown in Fig. 10, the groove 38 in the shuttlebar being disposed directly below the forming-bars to register therewith. The blade 71 is disposed in advance of the forming-bars,

and as the hinged frame is brought downv by the cam-pulley the paper which has been'y fed to the proper distance beyond the blade Just prior to come engaged by cam-guides 14 and 15 to be carried into latchi'ng'engagement with the shuttle-bar. 'The nose 37 of. 'said locking-bar is provided with a ridge 78, which in its forward travel engages the curved end'79 of anv inverted-V-shaped spring 80, secured at its bend' to apivot 81, one leg S2 thereofextending downward to the left of the forming-bars, theotherleg extending downward to the right thereof and terminating in the curvedend 79. A s the curved end 79 is carried upward byv the ridge 78` leg 82 is carried forward against"the` left upwardly-projecting endof the paper held inthe groove 38, and the nose 37 ofthe locking-bar folds the other upwardlyextending end 85 of the paper over the end 84 turned down by the leg 82, the nose remaining in this position with respect to the paper carriedin groove 38 of the shuttle-bar throughout thefvarious stages. This position J.

is best shown -in Fig. 3. The 'edges of the paper as thus folded extend a distance beyond the sides ofthe shuttle-banand during the next stage in the manufacture 'of the spool these extending edges are dared out#L wardly to form flaps against which the iiangeV rparts are to be secured,'as"will be outlined in la subsequent stage of'operation. The aring mechanism is operated and controlled by cam-pulley 5, which revolvesin the directionshown by the arrow. As best seen in Figs. 12 and 13, this cam-pulley is provided with camrollers 86 and 87, one on each side of the cam-V roller and diametrically disposed. These camrollers are adapted during revolution of camroller 5 to respectively engage the cam ends 88 and 89 of cam-arms 90 and 91 to cause longitu- A93 93 of sliding bars 94 94, adapted to reciprocate in bearings 95 95, are fulcrumed at an intermediate point to bearings 96 96, projecting from the frame of the machine. The tension-spring 92', disposed between arms 92 below the bearings 96, tends to retain said arms in a closed position. The bars 94 terminate in flaring-bars 994 99, the thickness of said bars being slightly greater than the height'of the opening of the folded paper core. ends of said flaring-bars are provided with wedge-shaped edges 100 100, and V-shaped slots 101 101 are cut into the edges near the end thereof. Transverse members 102 102 ICO IIG

The f bridge over the Haring-bars and are secured are secured to said transverse members and i pass forward between the bridging-walls of said members and the sides ofthe flaring-bars, having at their forward end V-shaped indentations 107 107, which register'with and normally lie in the V-shaped slots in the forward end ofthe flaring-bars. The spring-points 109 109 are bent inwardly and are cutv to a ends of the folded paper carried by the shuttlc-bar. 'The spreading action of the springs does not take place until the points of the springs have entered a slight distance into the opening of the folded paper. As they are now spread outwardly by the further forward travel of the flaring-bars the points ot' the springs engage the side walls of the projecting folded paper, flaring them out, while at the same time the wedge-shaped ends of the flaring-bars engage the ends of the top and lower walls of the folded paper to fiare them outward, thus forming Haps 110 at either end of the folded paper core against which the flanges are to be glued during a subsequent operation. The paper from which the flange portions are formed is fed in the shape of bands 111 from rolls 112, carried upon spools 113, mounted upon pivots 114, extending upward from the rear part of the machine-frame. One of these spools is mounted at either side of the shuttle mechanism, the paper being fed by feeding mechanism between feed-rollers 115 and guide-rollers 116. Ratchet-wheels 117 are secured to feed-wheel 115, and pawl-cranks 118 are provided at `their ends with pawls 119, adapted to engage theAratchet-wheels. Connecting-rodslZOlead from the pawl-cranks to crank-arms 121, secured to the top end of Vertical and downwardly extending shafts 122,Which terminate at their lower ends in crank-arms 123. As best seen in Figs. 2 and 16, the crank-arms 123 are actuated by means of cam mechanism associated with cam-pulley 5. A guideway 124 is secured to the bottom of the bed-plate of the machine, and a sliding bar 125 is adapted to reciprocate therein. A cam-post 126 extends downwardly from said slide-bar and engages camway 127, disposed on the periphery of cam-pullej7 5. This camway extends diagonally across the periphery of the campulley 5 and back again toward the left thereof, and as the cam-pulley revolves, as indicated by the arrow, the cam-post 126 travels p in said camway and the slide-bar 125 is rey tical shaft 122 to actuate the feeding mech- .are mounted in bearings 141.

anism. The paper after leaving the feeding mechanisms passes through guide-slots133 and adjacent to the guideways 19 19, passing by punch-openings 134 'and 135 through said guideways, the paper emerging from transverse guide-slots 136. Pockets 137 are cut into the walls of said guideways 19 between punch-openings 134 and 135 to hold Sponges 138, which may be kept properly moistened, these spon ges projecting forward into the path of the paper, moistening said paper on the inside face thereof. Punch-rods 139 and 140 Punch-rods 139 terminate in rectangular punches 143, the cross-section having the shape and size of the opening in the core portion of the spool. Punch-rods 140 terminate in punches 144, a cross-section thereof having the shape of a dange portion. Projecting forwardly from the forward faces of said punches 144 are ledges 145, having the. same shape as the punches 143. A shaft 146 connects the outer ends of the punch-rods, which are associated with cam-pulley 6, as best shown in Fig. 15. Levers 147 and 148 are fulcrn med in bearings 149 and 150, respectively, depending from the frame of the machine. A cam-shoe 151 extends vertically and downwardly from the arm 152 of lever 147. The top face at the inner end of arm 152 and the surface of the shoe 151 form cam-surfaces which are engaged by a cam-roller 153, mounted upon one side of cam-pulley 6. The arm 154 of lever 148 `terminates at itsend in a-hook-shaped part 155, the end of which terminates in a camshoe 156, extending vertically and .downwardly therefrom. The inner surface of said hook-shaped partrnay be circular and forms, with the surface of the shoe 156, a cam-bearing adapted to be engaged by a cam-roller 157, suitably disposed upon the opposite side of cam-pulley 6. As cam-pulley 6 rotates in the direction as indicated by the arrow the cam-rollers engage their respective cam-surfaces and separate the lever-arms 152 and 154, which terminate at their other ends in bearings 158, engaging shafts 146. `A tensionspring 150' connects lever-arms 154 and 152 to return them to their former position after actuation thereof, stop-posts 151 and 152, securedto said arms, serving to limit said spring to retain the camways upon said arms in a suitable position to be engaged by the camrollers. As the lever-arms are thus spread punches 143 and 144 are carried toward each other and pass through their respective punch-openings. Punches 143, which are disposed in advance of punches 144, punch pieces 159l out of the pape r,leavingan opening 143 in the paper having the size of the coreopening, said pieces falling through escapeopenings 159. The length of paper fed by the feeding mechanism during each revolution is equal to the distance between the centers of punches 143 and 144, and the openings cut into the paper by punches 143 are carried to aline with the center of punches IOO IIC

- the front face thereof enterLthe ropenings in the paper which have been cut into the paper by punches 143 and which have been carried to aline with said ledges byan actuation of the feeding mechanism. As. the punches 144 still travel forward the flanges 160 are punched ont of the paper and supported upon the ledges 145, which ledges enter the open-v ings 143 of the core portion, which by this time has been carried by the shuttle mechanism to aline with said punches. The ledges an ges are out therefrom and pressed against the gummcd faces ofthe flaps they arevcaused. to adhere thereto, and the spool is now completed. The punches are now withdrawn, and

the finished spool is supported upon the for' ward end of the shuttle-bar, which now appreaches the end of its stroke to assume the position as shown in Fig. 4, the cam-roller 7 having carried the finger 42 thereon to trip the latch 30, thus releasing the lockbar,which is pulled back by the spring 28 away fromthe bridge 35 on the shuttle. The shuttle thus being released is snapped backward over the edge of the bed-plate' by the spring 30, and theV finished spool carried upon the end thereof is delivered into a suitable receptacle.

The disposition of the camways which causes interrupted Vreciprocation of the shuttle mechanism across the face of the machine is shown on Figs. 1, 2, 3, and 4, Figs. 1, 2, and 4 showing the mechanism at the extreme right of its stroke and Fig. 3 showing said `periphery of cam-Wheel 7 and along the diagonally-disposed camway 9. As said camroller travels in camway 8 there is nomot-ion -of the shuttle-bar; but as said roller enters the diagonal camway 9 the shuttle-bar is carried toward the forward end of its stroke.

. During this forward travel of the shuttle-barV cam-pulley 4 rotates'to actuate the feeding mechanism, campost 51 being carried tothe (Shown in Fig. 6.) The cam-roller will have assumed the position ing become disposed to receive the formingbars, the cam-roller 13 having been carriedA bring the lock-bar to itsforward position to assist iu the folding operation. Cam-roller 13 now entersr the diagonal camway 10, disposed 'on the peripheryof cam-pulley 7', to carry the shuttle mechanism backward 'to bring the4 folded core portion carried thereby into alinement with the Haring mechanism' to be treated as hereinbefore outlined.` After having been carried to the flaring position cam-roller 13 enters the circumferential camway 11, the shuttle mechanism remaining at rest, while the cam-roller travels in said camway, during which travel the flaring mechanism is operated as shown in Fig. 12, cam-rollers 86 and 87 engaging their respective cam posts 90 and 91 to cause the operation of the flaring mechanism. The core portion of the spool is now completed, and cam-roller 13 entering the diagonal slot 12 carries the shuttle mechanism and the core portion carried thereby backward to a position Where said core portion lmay receive the flange portions. Cam-roller 13 after leaving the diagonal camway 12 renters camway 8, and during'its vtravel in said camway 8 the punches are operated as herei-nbefore described to provide Vthe core portion with flanges, whereupon the vfinger 42 trips latch 30 to release theA lock-bar to allow the shuttle to be snapped backward to deliver the finished spool, as before described.

Although I have described my invention as applied to a machine for automatically manufacturing paper spools, I'do not wish to limit it to such use thereof, as bythe mechanism employed similar articles may be readily manufactured. Changes may also readily be made in the construction ofthe various mechanisms without departing from the spirit of the invention. v
